I bought a digital designs S2. it does 2200 x1 @ 2ohms or 1100 x2 @ 1 ohm. I still have the red tops i just took them out because someone said they were the wrong type of batteries. so i figured why not just start over on the electrical. I currently have a stock 105 amp alt big three and two runs of 0 gauge going to the back. With the red tops on the Hifonics 1610d my voltage didnt flinch but i still thought i should start over.
right now with a 105amp alternator you will only get in your electrical system enough power to run 1512 watt maxed output . take a 200 amp alternator and do your math
200amps x 14.4 volts which is charging system output
200 x 14.4 = 2880 watts this would be peak or max output
.80% x 2880 watts = 2304 total wattage output your 200 amp altenator could produce
this first calculation is done on 100% efficiently but amps are not that efficient maybe 80%
is more realistic...
VITAL POWER - VP2500 - 15.9" X 9.3" X 6.8"
vital power batteries are design just for car audio. It blows the red top or yellow top batteries away. they are better than kinetic batteries also .... but cost is more
